HEADLIGHT FOR nuromonmns.

Specification of Letters Patent.

Patented Jan. 17, 1911.

To all whom it may concern: Be it known that we, WILLIAM H. HUN and ROBERT C. VRooM, citizens of the United States, residing at San Diego,.State of California, have invented certain new and useful Improvements in Headlights for Automobiles, &c., of which the following is a specification.

()ur invention relates to reflecting lamps and particularly headlights for automobiles and the like.

The main object is to throw a part of the light laterally so as to light up the sides of the road.

Another object is to provide simple and inexpensive means which may be readily attached to and adjusted to different -lamps for producing lateral deflection.

The invention consists in improvements, the principles of which are illustrated in the accompanying single sheet of drawin In its preferred form it consists pre erably of a lamp body having a source of light, a main projecting reflector at the rear, a diffusing reflector in front and a lateral deflecting reflector at one side of the diffusing reflector. Two of these lamps are usually and preferably provided 011 an automobile, one at each side. The laterally deflecting refiector of the right. hand lamp is on the left hand side of the lamp so as to deflect a part of the light to the right. flector of. the left hand lamp is on the right side of the lamp for deflecting a part of the light to the left.

In Figure 1 is a diagrammatic plan View of the front end of an automobile with two .plane ofthe door and out of contact with lamps with reflectors arranged according to our invention. Fig. 2 is. a horizontal sectional view of the lamp to be used on the left hand side of the automobile. Fig. 3, is Fig. 4, is a perspective view of one of the defiecting attachments. in Fig. l the right and left hand lamps are indicated by the numerals 1 and 2 respectively and the front end of the automobile indicated by the numeral 3.

The details of construction of the body and support of the lamp are unimportant. In the form illustrated the body 4 has a front door rim or frame 5 hinged at 6 and provided with a catch 7 and a suitable lens or glass 8 secured in any suitable manner.

, The character of the source of light is unimportant. We have=shown it here as a gas The deflecting re-..

burner 9. Back of this is the main concave projecting mirror 10 shaped and arranged in a suitable manner so as to project a substantial shaft of light straight forward. In front of the main mirror or reflector is a conical reflector 11 which serves to difi'use a part of the light from the burner and makes a sort of glow. The laterally deflecting mirror or reflector 12 is preferably arranged so that it does not interfere with or subtract from the main shaft of light projected forward by the main mirror 10. This deflecting mirror is preferabl concaved slightly but it may be flat if esired. From' the position of this mirror 12 in F i 2 and 3 it will be seen that a part of the lig t coming directly from the burner 9 will be deflected laterally of the lamp and as a definite beam or shaft independent of the diffused light from the mirror 11.v

So far as a broad idea of this invention is concerned the deflecting mirror 12 may be constructed and mounted in any suitable manner. The preferred construction however is that illustrated in Fig. 4. The mirror is carried by a frame or support made of wire which has the arms 13, 13 terminating in tips 14, 14 which are adapted to be insorted in any one of a number of holes in the top and bottom of the rim 5 of the door of thelamp inside of the glass 8. This sup port is elastic so that it may be conveniently sprung into place and retained without other means of attachment. A part of the wire is formed into a loop-like guide post 16 which bent at an angle to the arms 13, 13 so as to bring the mirror inside of the vertical the front glass 8. A stud or screw shank 17 carried by the mirror projects between the sides of the 100 16 and a thumb-nut 18 is provided for c amping the mirror 12 in place. By this construction the mirror may be adjusted backward or forward to obtain the proper lateral deflection. -The wire su porting frame may also be bent to a consi erabledegree to correspond with the size and shape of the interior of the particular lamp to which it is to be attached. Thus it will be seen that the attachment is adapted to difl'erent lamps and thus constitutes an article of manufacture salable independently of the other parts of the lamp and intended to be adapted to any suitable form of lamp.

The advantages of the invention willbe apparent to those who are acquainted with mirror.

source of light, a front glass for the. casing and a deflecting mirror arranged inside the casing behind the front glass in front of the source of light and at one side thereof for horizontally deflecting to the opposite side and out through the front glass, a portion of g the rays from the source of light.

2. In a lamp, a main projecting mirror, a diffusing mirror forward thereof, and a laterally deflecting mirror arranged at one side of the diflusing mirror to deflect a partof v the light to the opposite side.

3. In a lamp, a source of light 9, a main projecting mirror 10 in rear thereof, a front glass 8 and a laterally deflecting mirror 12 arranged at one side between the source of light and the front glass for deflectinga portion of the light horizontally tothe opposite side through the front glass.

4. In a lamp, a main projecting mirror, a laterally deflecting mirror arranged at one side thereof, for deflecting a portion of the light to the -o posite side, said deflecting mlrror being a justable horizontally in said lamp toward and from the mainprojecting 5. A reflecting lamp comprising a body, a front door hinged thereto, a main projecting mirror mounted in the body of the lamp and a laterally deflecting mirror supported by the inside of the front door of the lamp and movable therewith.

6. In a lamp, a main. projecting mirror, a conical di'flusing mirror and a substantially vertical deflecting, mirror arranged at one side of the diffusing mirror for throwing an independent lateral beam of light.

7. In a lamp, a main -projecting mirror and a frame having supporting arms and a guide post and a deflectlng mirror clamped to said guide post and adjustable thereon in relation to said projecting mirror.

8. In a lamp, a source of light, a projecting mirror in rear thereof, a front glass and an angularly adjustable deflecting mirror arranged at one side between the source of light and the front glass for deflecting a part of the light to the opposite side.

9. A lamp attachment comprising curved wire arms 13, 13 having tips 14:, 14 bent at an angle thereto and extending outwardly in .the general direction of the radii of the curved arms, a 0st 16 extending at an angle to the plane 0 the arms and a mirror 12 clamped to said post, said tips being adapted to be inserted in'recesses at the front of a lamp so as to bring the mirror in position at one side of the lamp to deflect a part of the.

light across the lamp body.
